Product details
Overview
X9317WS8Z-2.7T1 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 2.7V to 5.5V supply operation. It implements a 99-element resistor array with temperature-compensated end-to-end resistance tolerance of ±20%, wiper resistance ≤400Ω at 2.7V, and standby current <5µA. It serves as a three-terminal voltage divider or two-terminal variable resistor in precision analog trim applications.
For engineers reviewing the X9317WS8Z-2.7T1 datasheet, X9317WS8Z-2.7T1 pinout, X9317WS8Z-2.7T1 application, or X9317WS8Z-2.7T1 equivalent, key selection criteria include its 8-pin SOIC package, 10kΩ end-to-end resistance, 3-wire up/down interface timing (tCYC = 2µs), ratiometric temperature coefficient of ±20ppm/°C, and guaranteed nonvolatile recall on power-up.
Technical Context
The X9317WS8Z-2.7T1 integrates a 7-bit up/down counter, decoder, and solid-state resistor array with make-before-break wiper switching. Its control logic responds to CS (chip select), U/D (direction), and edge-triggered INC inputs - no clock required. Wiper position is stored in nonvolatile memory only when CS transitions HIGH while INC is HIGH.
It operates as a true analog potentiometer: RH and RL form fixed terminals; RW is the movable wiper terminal with typical series resistance of 200Ω at 5V and ≤1000Ω at 2.7V. The device exhibits ±1% absolute linearity and ±0.2% relative linearity across all 100 taps, with noise performance of –120dBV referenced to 1kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10kΩ ±20% - defines full-scale analog range for voltage division or current limiting |
| Supply Voltage Range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V systems without level shifting |
| Wiper Resistance | ≤1000Ω at 2.7V - ensures minimal signal path degradation in low-voltage bias networks |
| Standby Current | <5µA - supports ultra-low-power operation in battery-backed or energy-constrained designs |

Pinout & Package
Package: 8-pin narrow-body SOIC (M8.15E), RoHS-compliant, 0°C to +70°C operating temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment input | Negative-edge-triggered control line; toggling moves wiper up/down based on U/D state |
| 2 (U/D) | Up/Down direction control | Logic level selects wiper movement direction during INC transitions |
| 3 (RH) | High terminal | Fixed end of resistor array; connected to higher potential in voltage divider configuration |
| 4 (VSS) | Ground reference | Return path for internal logic and analog circuitry; must be low-impedance |
| 5 (RW) | Wiper terminal | Movable contact point; output node for adjustable voltage or current; series resistance ≤1000Ω |
| 6 (RL) | Low terminal | Fixed end of resistor array; connected to lower potential or ground in voltage divider |
| 7 (CS) | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store when rising edge occurs with INC HIGH |
| 8 (VCC) | Supply voltage | Power input for logic and analog sections; accepts 2.7V–5.5V; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap position across power cycles; eliminates need for boot-time reinitialization |
| 3-wire serial up/down interface | Requires only three GPIOs - no clock, no SPI/I²C peripheral needed - simplifies MCU integration |
| Temperature-compensated resistor array | ±20ppm/°C ratiometric tempco ensures stable voltage division ratio over industrial temperature range |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions; critical for glitch-free bias control |
| Low-power CMOS design | Standby current <5µA and active current ≤80µA enable use in always-on sensor front-ends |
| 100-tap resolution with ±1% linearity | Delivers precise analog trimming accuracy comparable to high-grade mechanical potentiometers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | I²C interface, 256-tap resolution, 10kΩ, 2.7–5.5V; higher ICC active current (120µA); no built-in nonvolatile store (requires external EEPROM) | Suitable for systems with I²C bus availability and need for finer resolution; requires additional firmware overhead for persistent storage | Select when I²C infrastructure exists and 256-step granularity outweighs self-contained NVM benefit |
| MCP41HV51-103 | 100kΩ end-to-end resistance, SPI interface, 2.7–5.5V; includes volatile wiper latch but no nonvolatile memory; higher wiper resistance (≤1.5kΩ) | Better suited for high-impedance bias networks where 100kΩ loading is acceptable; lacks automatic power-up recall | Choose for SPI-based designs needing higher resistance values and where host MCU handles calibration persistence |
Compared with AD5170BRMZ-10 and MCP41HV51-103, the X9317WS8Z-2.7T1 delivers autonomous power-up behavior, simpler GPIO-based control, and guaranteed 100-year data retention - making it optimal for unattended, calibration-critical analog subsystems where firmware complexity must be minimized.

This extended low-voltage capability enables direct integration into modern low-power embedded designs while maintaining full functionality including nonvolatile store and wiper movement.
Does the X9317WS8Z-2.7T1 retain its wiper position after power loss?
Yes, the X9317WS8Z-2.7T1 stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This behavior is guaranteed by design: the last valid wiper setting is retained for up to 100 years and restored within 5µs after VCC stabilizes, eliminating boot-time reconfiguration.
How many wiper positions does the X9317WS8Z-2.7T1 support?
The X9317WS8Z-2.7T1 provides exactly 100 discrete wiper tap points, corresponding to a 99-resistor-element array. Each step represents 1% of full-scale resistance, with ±1% absolute linearity and ±0.2% relative linearity verified across the entire range.
What package type is used for the X9317WS8Z-2.7T1?
The X9317WS8Z-2.7T1 is housed in an 8-pin narrow-body SOIC package (JEDEC MS-012, drawing M8.15E), RoHS-compliant, with 1.27mm lead pitch and 0°C to +70°C commercial temperature rating. Its footprint is compatible with standard SOIC-8 assembly processes and reflow profiles.
Can the X9317WS8Z-2.7T1 be used as a two-terminal variable resistor?
Yes, the X9317WS8Z-2.7T1 can operate as a two-terminal variable resistor by connecting either RH or RL to RW externally, leaving the unused terminal open or grounded. In this mode, it functions as a digitally adjustable current-limiting or gain-setting element with 10kΩ maximum resistance and ≤1000Ω wiper resistance at 2.7V.
